Hi, Thanks for the replies. Still no joy, this is strange behaviour. We don't want to enable relaying totally, because of the security risks. Yet its still a problem if we enable it for specific IP addresses, it doesn't work. We can enable routing to specific external domains, and this works.
Anyway, it appears to be either a JavaMail or Exchange Server problem, so I'll keep looking there.

You need to restart the internet mail service (in control panel/services) for the change to take effect. -- Best regards, Christoph mailto:[EMAIL PROTECTED]
